/**
 * Register a guard for a collection. Guards run on every `put()` /
 * `delete()` for the named collection (after permissions, before
 * encryption) and may:
 *
 *   - `check` — block writes by throwing (typically `RecordLockedError`)
 *   - `frozenFields` — freeze specific fields once a condition is true
 *   - `amendment` — declare an authorized-override path with invariant
 *
 * Pass the returned handle to `createNoydb({ strategies: [...] })`.
 *
 * @see docs/superpowers/specs/2026-05-18-guards-design.md
